18 16 Technical appendix Installation instruction BÜCO s universal joints and shaft joints are now and will be in the future indispensible and versatile components for transmitting rotary motions. 1. Correct fork position: when using two single universal joints make sure that the two inside forks or brackets (for bracket versions) are in flat formation, as in the case of double universal joints. If two shafts, which are inclined towards each other at a given angle, are connected to each other via a universal joint, and if one of the shafts rotates with a constant angular speed, then the other shaft rotates with a variable angular speed. This irregularity of motion - which is also called gimbal error causes the rotating angle to advance and lag alternately, thus effecting the second shaft to rotate with sinusoidal fluctations. The greater the deflection angle a, the greater the non uniformity of the rotating motion. right: forks in flat formation 2. The deflection angles at both ends must be equal. wrong: fork plane turned by 90 turned by 90 For this reason, single universal joints are only used when variable rotary motion is permissible. The non uniformity of motion can be compensated by using two single universal joints in sequence or by using a double universal joint. When properly installed the second universal joint can compensate the irregular motion of the first one under the following conditions as enumerated by DIN 808: right: the angle α is equal everywhere wrong: the angles α and ß are not equal 3. The driving and driven shafts may only be shifted in directions parallel to the shafts. axis axis right: axis 1 is parallel to axis 2 wrong: axis 1 is not parallel to axis 2 4. The bearings of the shaft joint or of the double universal joint should be positioned as close as possible to the universal joints. The shaft joints are delivered without pinholes and clamping studs. The length of the clamping studs is determined by the outer diameter of the universal joint; it must be flush when set. right: the bearings are as close as possible wrong: the bearings are not close enough

19 17 Technical appendix Maintenance and lubrication To ensure trouble-free employment of BÜCO s precision universal joints and precision shaft joints with friction bearings or brackets you should lubricate them at regular intervals. BÜCO s precision universal joints with needle bearings are maintenance-free and, due to their permanent lubrication, are preferably used in machine components difficult to access. Caution: BÜCO s precision universal joints and precision shaft joints are ready for use and are lubricated with a lithium saponified, extreme pressure lubricant on a mineral oil base. Temperature range lubricant: from -30 to +125 C (permanent lubrication) Peak temperature lubricant: maximum 140 C Please use lubricants with the same specification for re-lubrification. Lubricating points Lubrication is required at least once daily for permanent operation at the lubricating points marked with arrows. For friction bearings and bracket version this means all the sliding parts on the cube, the fork piece and bearing pins and as well as for shaft joints the sliding parts of the extendable splined profile. In harsh environments, the sliding parts should be protected against fibrous particles and steam by means of a folding bellow. Permanent self-lubrication for an indefinite time is achieved by filling the folding bellow with a lubricating grease. Note: Maintenance work should be carried out at regular intervals; preferably while carrying out maintenance work on other machine parts. In such cases, we recommend that noise and backlash tests be conducted, or if the working noise and/or the backlash of the joint and profile parts deviate from the standard values. Instructions for BÜCO s precision universal joints with needle bearings: BÜCO s precision universal joints with needle bearings in accordance with DIN 808-W are used wherever high transmission performances together with precise load transmissions at high speeds (of up to max r.p.m.) are required. Power transmission is through the center of the universal joint via a forged spider, whose four polished studs are contained in needle bearing bushes sealed off by sleeves. The special roller bearing grease is inserted during assembly and guarantees that BÜCO s precision universal joints with needle bearings remain absolutely maintenance-free due to permanent lubrication.

20 18 Technical appendix Calculating the dimensions of the universal joints G The selection of a universal joint ist not determined exclusively by the max. torque to be transmitted. There are also other operative conditions which must be taken into account, such as impact load, angular ratios, angular velocities, etc. The diagrams presented below give approximate preliminary values for calculating the dimensions of the universal joints and contain the corresponding standard values. Figure 1 shows the power and torque values transmitted by single precision universal joints during permanent operation with a deflection angle of α = 10. Note: The loads to which double universal joints are exposed may only be about 90 % of the corresponding values for single universal joints. This also applies to shaft joints. Figure 2 shows the adjustment value to be taken into consideration for greater deflection angles. For deflection angles less than 10, e.g. between 0 to 5 you may increase the standard power value shown in figure 1 by 25%. There are no general standard values for precision universal joints with friction bearings, for which it is possible to specify the service life, as the stress and strain to which the friction surfaces are exposed is determined by the regularity of the lubrication intervals. Fig. 2: Adjustment value in relation to the deflection angle Example Given values: the power to be transmitted P = 1,5 kw speed n = 250 r.p.m. deflection angle α = Calculation: adjustment value from fig. 2 n = 0,45 P 1,5 standard power P = = = 3,3 kw n 0,45 Figure 1 yields for n = 250 r.p.m. and 3,3 kw: shaft joint E 32 x 63 (or E 40 x 63) with the admissible torque value of M = 125 Nm. Fig. 1: Power diagram for precision universal joints with friction bearings in accordance with DIN 808-G The universal joints are delivered without pinholes and clamping studs. The length of the clamping studs is determined by the outer diameter of the univseral joint; it must be flush when set.

21 19 Technical appendix Calculating the dimensions of the universal joints W Figure 5 shows the service life of BÜCO s maintenancefree precision universal joints with needle bearings depending on the impact factor (e.g. standard value 1.5 for an electromotor drive without flexible coupling), the adjustment value for the deflection angle and the torque value to be transmitted. Figure 6 shows the adjustment value for calculating the service life of BÜCO s maintenance-free precision universal joints with needle bearings. Note: The loads to which double universal joints are exposed may only be about 90% of the corresponding values for single universal joints. This also applies to shaft joints. Fig. 6: Adjustment values with relation to the deflection angle f Z = impact factor (see technical questionnaire) n = adjustment value (from figure 6) M = torque value to be transmitted M red = M x f Z x n Fig. 5: Service life diagram for precision universal joints with needle bearings DIN 808-W Example Given values: the power to be transmitted M = 70 Nm speed n = 1400 r.p.m. service life L = 500 h deflection angle α = 20 impact factor f Z = 1,5 adjustment value from fig. 6 n = 1,1 reduced torque M red = M x f Z x n = 70 x 1,5 x 1,1 = 116 L x n = 500 x 1400 = = 70 x 10 4 Figure 5 yields: universal joint E 32 x 63. The universal joints are delivered without pinholes and clamping studs. The length of the clamping studs is determined by the outer diameter of the univseral joint; it must be flush when set.

22 20 Technical appendix Calculating the dimensions of the universal joints bracket version Figure 3 shows the power and torque values transmitted by single precision universal joints (bracket version) during permanent operation and with a deflection angle of α = 10. Figure 4 shows the adjustment value to be taken into consideration for greater deflection angles. For deflection angles between 0 to 5 you may increase the standard power value by 25%. Fig. 4: Adjustment values with relation to the deflection angle Example Given values: the power to be transmitted P = 0,540 kw speed n = 300 r.p.m. deflection angle α = 30 Calculation: adjustment value from fig. 4 n = 0,45 standard power P = P 0,540 = = 1,2 kw n 0,45 Figure 3 yields for n = 300 r.p.m. and 1,2 kw a universal joint E 16 x 32 with the admissible torque value of M = 40 Nm. Fig. 3: Power diagram for precision bracket joints with friction bearings The universal joints are delivered without pinholes and clamping studs. The length of the clamping studs is determined by the outer diameter of the univseral joint; it must be flush when set.
